Ever wanted to check the time, but either (a) don't have a watch, or (b) are in a situation where it would be socially awkward to do so? Don't worry, here's a solution! You can have your phone tell you the time by vibrating! iPhone 7 and Up. A long vibration means a value of 5 for the current digit, and a shorter one means 1. Add them up in your head, then you have a digit of the time. (It goes through all of them, though, duh.)
